First Claim
1. A heat unit for use with a heat source, the heat unit comprising:
- a plurality of rectangular panels coupled to form an open-ended polyhedron, each adjacent side being coupled together by means of a folding hinge, the polyhedron defining the heat unit'"'"'s interior; and
a brace comprising a rigid member with a flange on an end thereof, the brace temporarily extending between two panels with the flange interlocking with an aperture through one of the two panels to render the open-ended polyhedron rigid.

Abstract
A portable heat unit is described. The heat unit is useful as an oven, barbecue, griddle, etc. The heat unit comprises a body, a lid, a cooking support member such as a grill rack or oven plate and a brace. The body comprises a number of rectangular panels joined to form an open-ended polyhedron such as a box. The panel joints are movable, and preferably comprise piano hinges, thus rendering the body collapsible. When in use, the stand is rendered noncollapsible by installation of the brace. The brace comprises a rigid member which is placed between two panels to permit control of the burning of the fuel, heat flow, temperature and to define an opening through which the fuel and food may be conveniently accessed.

13. A collapsible heat unit comprising:
-
a heat source; a collapsible body into which the heat source is disposed, said collapsible body being comprised of four panels forming a rectangular structure, each adjacent panel being coupled together by means of a folding hinge, a lid and a bottom panel to provide a full enclosure; and a nonextensible member temporarily interacting with two opposing panels of said rectangular structure by means of a flange at one end and an extended edge at the other end thereof and extending between the two panels with said flange interacting with an edge of an aperture through one panel and said extended edge passing through a slot in the other panel to render said collapsible body noncollapsible and to support said heat source, whereby a rugged, easily stored, collapsible heat unit is provided.

14. A heat unit comprising:
-
a cooking support member for supporting food to be heated; a collapsible body into which said support member rests, said collapsible body being comprised of four side panels forming a rectangular structure, each adjacent panel being coupled together by means of a flatly folding hinge; and means for temporarily rendering said collapsible body noncollapsible comprising a rectangular tray temporarily attachable along ends of said tray with opposing panels of said heat unit by means of an end flange on said tray interacting with an aperture through one of said panels; whereby a rugged, easily stored, collapsible heat unit is provided. - View Dependent Claims (15, 16, 17)
